Hello, I'm superjack. Basically, I made around 40+ maps, and you haven't seen most of them because they're complete shit. (Sometimes they don't even work - they crash the game.) However the other ones you have maybe seen around, SJHoM, SJGlav, Deserts, headache, notso, or that big library CTF map, those are all maps I made.
Also, I made the NoX wikia, host the domain of this site, am a professional pianist, won 4 tournaments (one third prize, and one warrior tournament which you can find on youtube, and one clan battle) and hosted NoX for ages long because of my obsession with the game.
I'm 20 years old now, studying piano on a conservatory.
